9 Claims.

This invention relates to a reconditioned shingled roof and particularly to a novel and improved spacer device for insertion under the shingles to raise their exposed butt ends slightly above the undersurface and provide a vent channel therebeneath after the roof has been reconditioned.

The invention is an improvement upon my Patent 2,171,850 of September 5, 1939, which is incorporated here as a part of the disclosure for showing the manner of coating and surfacing the shingled roof after the spacers have been inserted in place.

For a better understanding of the invention, reference may be made to the accompanying drawing in which:

Fig. 1 is a perspective View of a portion of a shingled roof, with the spacer inserted, prepared for reconditioning;

Fig. 2 is a sectional view on line 2 2 of Fig. 1;

Fig. 3 is a perspective view of one of the spacers embodying the invention; and

Fig. 4 is a perspective view of a portion of va reconditioned roof embodying the invention.

Referring specically to the drawing in which like numerals are used to designate like parts the roof is preferably swept to remove dirt and loose granules from the prepared asphalt shingles I which are nailed at 2 in overlapping courses on the wall or roof deck 3.

Spacers 4 are inserted under each shingle, preferably between its side edges and to one side of the space 5 between adjacent shingles. The spacers are deformed to provide a channel side 6 opposite to projection 1 between legs 8. No particular shape of the channel and projection is necessary. It may be triangular, concavoconvex, hexagonal, and, if desired, the width of the spacer may be of suiiicient extent to provide a plurality of channels and projections alternately disposed. A spacer with one channel opposite a projection has been found especially ecient.

The spacers may be inserted with their bottom edges iiush or above the bottom edges of the butt ends of the shingles, but are preferably inserted so that a portion of the ends will be exposed and extend below the butt ends lof the shingles. The operator can thereby readily see where spacers have been and have not been inserted, thereby avoiding any inadvertence in not applying spacers beneath allthe shingles.

The channels in the spacers provide vents beshingles in the roof, including their side andv neath the shingles, and the projections opposite to -the channels are of a height slightly exceeding the thickness of the asphalt coating 9 to avoid any possibility of the end of the channel being closed by the asphalt coating.

The asphalt coating is applied in a layer of uniform thickness conforming to the outline or design of the individual shingles. After the asphalt coating is applied, granular mineral material I0 is spread over and partially embedded in the coating. The asphalt coating and granular mineral material covers the entire surface of the butt edges.

The spacer may be provided with a tooth or teeth Il on any portion which is in contact with the shingle in order to positively hold same in its inserted position. The tooth may be conveniently formed by stamping a portion from the crown of the projection and bending it upwardly. The spacers may be made from any material although sheet metal or spring steel is preferred.

While I have described with particularity one specific spacer, it will be understood that there may be various changes without departing from the spirit of the invention.

I claim:

1. A reconditioned shingled roof comprising overlapped shingles, a channeled spacer under the shingles to raise portions of the overlapped shingles and maintain a drainage vent between the spacer and the shingles, and a weather protecting surface applied to the vented shingles.

2. A reconditioned shingled roof comprising overlapped shingles, a channeled spacer under the shingles to raise portions of the overlapped shingles and maintain a drainage vent between the spacer and the shingles, a waterproof coating applied to the vented shingles, and weather surfacing materials embedded in the coating.

3. A reconditioned shingled roof comprising overlapped shingles and a channeled spacer under the shingles to raise portions of the overlapped shingles and maintain a drainage vent between the spacer and the shingles.

4. A spacer for venting shingled roofs comprising a body having a channeled side adapted to separate shingles in adjacent rooiing courses and maintain a Vent therebetween.

5. A spacer for venting shingled roofs comprising a body having a channel in one side opposite to a projection on the opposite side adapted to separate shingles in adjacent roofing courses and maintain a vent therebetween.

6. A shingled roof comprising overlapping vented shingles, a portion of the lower edges of said shingles raised above the level of the remainder of said lower edges, said raised portions constituting drainage vents for the area underneath said shingles, a spacing material to retain said raised portions in their elevated portions and provided with a channel to maintain said drainage vents open, and the remaining edges of the shingles and the contacting portions of surrounding shingles sealed against Water admission.

7. A spacer for venting shingle roofs comprising a body having a channeled side adaptedto separate shingles in adjacent roong courses and maintain a vent therebetween, and means for impinging the spacer to the shingles.

8. The method of reconditioning shingled surfaces comprising positioning a channeled member under the lower edge of the shingles in the overlapping course to provide a vent and drain, coating the shingle surfaces with a tacky adhesive, and then embedding granular material in the coating.

9. A reconditioned shingled roof comprising overlapped prepared asphalt shingles, a channeled spacer under said shingles intermediately of their side edges to raise portions of the overlapped shingles and maintain a drainage vent between the spacer and the shingle, and a Weather protecting surface applied to the vented shingles.
